Abstract
1. Радиолокационная станция с синтезированием апертуры и квазинепрерывным излучением, содержащая первый смеситель, первый вход которого соединен с выходом генератора частотно-модулированного сигнала и через передатчик (усилитель мощности) с передающей антенной, а второй вход через приемник (усилитель высокой частоты) соединен с выходом приемной антенны, выход смесителя соединен последовательно с фильтром низкой частоты и аналогово-цифровым преобразователем и процессором, в которых реализовано преобразование сигнала в цифровую форму и синтезирование апертуры антенны путем сжатия сигнала по дальности, компенсации траекторных нестабильностей и гармонического анализа, а также содержащая навигационную систему и индикатор оператора, отличающаяся тем, что в нее введены циркулятор «прием-передача», включенный между усилителем мощности и передающей антенной, при этом второй выход циркулятора последовательно соединен со вторым приемником (вторым усилителем высокой частоты), вторым смесителем, вторым фильтром низкой частоты, вторым аналого-цифровым преобразователем и процессором; аттенюатор, включенный между приемной антенной и первым приемником; синхронизатор, вход которого соединен с задающим генератором, а выходы со вторыми входами первого и второго приемников и управляющим входом аттенюатора.2. Радиолокационная станция с синтезированием апертуры по п.1, отличающаяся тем, что передающая и приемная антенны установлены на платформе с приводом стабилизации, подключенным к аналого-цифровому преобразователю и процессору, третий вход которого подключен к выходу навигационной системы носителя РЛС.1. A radar station with aperture synthesis and quasi-continuous radiation, comprising a first mixer, the first input of which is connected to the output of a frequency-modulated signal generator and through a transmitter (power amplifier) with a transmitting antenna, and the second input through a receiver (high-frequency amplifier) is connected to the output receiving antenna, the mixer output is connected in series with a low-pass filter and an analog-to-digital converter and processor, in which the signal is converted to digital form and synthesizing the antenna aperture by compressing the signal in range, compensating for trajectory instabilities and harmonic analysis, as well as containing a navigation system and an operator indicator, characterized in that it includes a receive-transmit circulator connected between the power amplifier and the transmitting antenna, while the second output of the circulator is connected in series with a second receiver (second high-frequency amplifier), a second mixer, a second low-pass filter, a second analog-to-digital converter, etc. tsessorom; an attenuator connected between the receiving antenna and the first receiver; a synchronizer, the input of which is connected to the master oscillator, and the outputs with the second inputs of the first and second receivers and the control input of the attenuator. 2. The aperture synthesized radar according to claim 1, characterized in that the transmitting and receiving antennas are mounted on a platform with a stabilization drive connected to an analog-to-digital converter and a processor, the third input of which is connected to the output of the radar carrier navigation system.
